van ons moeke voor 12-tal personen.


4 ajuinen
6 teentjes knoflook
10 stengels witte selder
10 (gemiddelde grootte) wortels
2 aubergines
2 rode paprikas
2 courgetten met schil
2 bakske verse champignons (=500g)
1 fles tomatenpuree (biotime)
2 kartonnekes tomaten coulie (=500g)
2 groentebouillonblokske
1 kruidenbouillonblokske
2 eetlepels spaghettikruiden
1 bakske gezouten spekskes (=100g)
300g pure americain (ongekruiden)
500g gedroogde lasagne (1 doos benito, “zonder voorkoken”, plat of geribbeld)
500g gemengde geraspte kaas
een beetje afsmakende geraspte kaas (oude of parmezaan)


De groenten stoven, van hard naar zacht.
Beginnen met ajuinen, wortels — terwijl de rest snijden.
courgette, aubergine, eindigen met de champignons.

Apart het spek en de americain (rillen) uitbakken, goed gaar.
Bij de saus doen op ‘t einde.

Gewone bechamelsaus (= witte saus) maken (zie boek van den boerinnenbond)

Stapelen van de lagen tot de ovenschotel bijna vol is.

1. Beginnen van onder met een klein beetje witte saus
2. een laag lasagne vellen
3. een laag groentensaus
4. een laag bechamelsaus
5. een laag gemengde gerastpe kaas
herhaal vanaf laag 2 tot de schaal bijna vol is.

Eindigen met als bovenste lagen 2x saus en een laag gemalen afsmakende kaas.

45 minuten bakken in de oven op 150 of 175 °C

Je kan dit gerecht vooraf klaarmaken, en een nachtje in de frigo bewaren, en dan afbakken de volgende dag. Als je het al gebakken hebt, kan je het terug opwarmen in de microgolf (15minuten op 750Watt)

Nodig wat vrienden uit en lekker smullen.

It’s saturday November 8th, 4:52 and I’m wide awake in bed. These are the times that really good (!?) ideas begin popping in my head. Today I felt the need to write some of them down.

A (web-) application to consolidate contact-information.

Yesterday evening, I was looking at how the Google Contacts API works. At that time I began to realize how usefull it would be to have some kind of application that consolidates contacts from different sources. The contacts I’m thinking about could come from outlook, gmail, yahoo, linked-in, netlog, facebook, plaxo, myspace, adressbook, windows live mail, you name it. I still had not registered the free domain name that comes with my new hosting, so – what the heck – I just registered in true web 2.0 style, just in case I ever want to create such an application.

Batteries to reduce stand-by costs of appliances

What I was thinking – not yet done the math – is that it could be cost-effective to use of-the-shelve batteries (AA) that are quite powerful, yet cheap to reduce stand-by costs of appliances.

The Idea is that when a led and IR-receiver of for example a tv-set are to be powered, an amount of energy is wasted in the conversion from 220 alternating current (AC) to low voltage direct current (DC). So to cut that cost a fairly simple technique could be used. Let me elaborate.

Take a simple electronics circuit that houses some functionalities you want in your appliance. Power that circuit with a battery and add some logic to make sure the battery doesn’t completely drain.

For example, you want to be able to turn on and off your TV-set using the remote. What you need than is a IR-receiver. The TV-set would remain plugged in. A circuit with the receiver, a voltage meter, some logic and a relay would be needed.

When you turn off the TV – using the remote – it will go into a stand-by state. Lets take the power to support this state from a battery. The switching circuit would – in case enough power is available from the battery – completely cut power to the tv-set using a simple relay, from that time no more energy from the grid is consumed. When the battery is losing its charge, at a certain threshold, the circuit could restore power to the tv-set, such that the stand-by state is powered from the grid, and the battery is charged. (The battery would be charged when the tv is on too, of course)

A fail-over would be in place, such that in case no battery was present, or when the battery is worn out, your tv would still work, it would than just fall back to using the grid to power its stand-by state. The battery should have to be user-servicable.

Now for the math (this is just guessing…)

  • Lets suppose that you need 1 new batteries each year, because they will wear out eventually. 4 rechargable NiMH AA batteries of 2300 mAh can be found for a price as low as 4€. So 1€ per year.
  • The electronics are really simple, so in the full cost of a TV-set negligible, but lets add 10€, to be on the safe side. Let’s also suppose that you keep your TV-set for 5 years, so this costs 2€ per year.
  • Add some extra cost for charging the batteries, what you would normally not do. (I don’t really know how I would calculate this.)
  • Lets suppose that the batteries can power the stand-by state of a tv-set for 3 weeks on a single charge. (I don’t really know how much power it would consume, but I guess this estimate is rather conservative)
  • Lets suppose that the tv-set is used at least every other day, this would mean that the batteries would never become empty, and that all stand-by cost would be cut. The batteries would trickle-load, which would mean that the extra energy used to keep the battery charged, while watching tv, would be negligible. (This is kind of cheating, because the tv-set would consume a little more energy while it is on)
  • I just made all this up… If someone has real data, please comment!

Cost per year: 3€

Energy saved per year: according to 10€

this means 7€ saved per year. This doesn’t seam like much, but how many devices have you got, that are on stand-by?

If government would promote this, and everyone starts using this kind of technology (on more than just tv-sets) it would globally really make a difference.

It would even be better if it were possible to retrofit this kind of technology to existing devices!

Just invent a battery-enabled switchbox with a remote, put it between the TV-set and the grid and there you have it. It would cost a bit more, because the charging must now be done, either outside the box, or the switchbox would need a charging circuit.

The downside of using batteries of course is that they need to be recyclable, and I don’t know how well they are.

Another thought on low-voltage direct current

Ok, so how many appliances and devices in your home use low-voltage direct current? If I think about it: A lot. Every device that has an adaptor (separate power supply), that has some led’s or clock showing…

So, microwave, alarmclock, PC and peripherals, telenet-devices (cable modem, splitter, amplifier, digibox, networking equipment (Powerline Ethernet)), tv, dvd player, stereo, radio, battery chargers, mobile phone chargers, electric toothbrush, digital picture frame,…

My thought was: couldn’t it be cost-effective to have 1 central, high quality, efficient, powerfull “power supply” in the house, that all these other devices could get their DC from?

I am aware though that transporting low-voltage, potentially high current electricity over a distance is a problem due to resistance, but I’m talking in the scope of a home. I’m also aware that all these devices have different requirements qua voltage, current, what have you,… so some smart sockets would be needed.

I’m not going to do the math on this one, because I simply don’t have any data.

I’m going to try and get some sleep…
